Hello-
Just wondering if anyone on the forum knows if a '48 grille for a standard chevy was the same for the COE trucks of that year. Thanks for your time.

COE had a different grille. If you haven't found the site http://chevy.tocmp.com has Chevy manuals on-line for most models through 1959. I checked the master parts book for 1929-1954. Direct link to the page http://chevy.tocmp.com/1929_57chevyparts/57cmpc0178.htm
